OUT! PetCare Advanced Urine Destroyer Cleaning Spray for Dog and Pet messes uses enzymatic and pro-bacteria technology to blast messes off the face of the earth—or at least your carpet. Advanced Severe Urine Destroyer uses a natural Pro-Bacteria and enzyme formula that is 3X-concentrated to eliminate urine stains and odors and pheremones. Quickly neutralizes odors instead of covering them up and eliminates remarking so pets won't revisit and resoil the same spots. It discourages the growth of bacteria and germs and helps prevent repeat marking by removing the pheromone scent. Effective on old and new problem areas, and is ideal for any water-safe surface like carpeting, rugs, upholstery, fabrics, tile, sealed wood, plastic, vinyl, concrete, mattresses, and trash containers. Safe around pets and children when used as directed.
